Is the 1.0 PureTech reliable?

It is a simple naturally aspirated three-cylinder, but with two documented weak points: oil consumption through the piston rings, which Stellantis acknowledges across its entire production (2012-2016), and the oil-bath timing belt it shares with the 1.2. It is only recommended with a full service history, a consumption test and a checked belt.^[1][2][3][4]

Is the 1.0 TCe / SCe reliable?

The 1.0 TCe/SCe (H4D/H4Dt) is a simply designed three-cylinder with reasonable reliability. Its most-cited fault is a noise or vibration from the turbo wastegate; the ECO-G (LPG) version adds its own gas-management faults and a 2023 recall over a risk of leaks and fire from the tank. An isolated case of a failed high-pressure pump is also documented, and no oil consumption pattern.^[5][6][7]
